New liquid CO2 pressure booster systems from Linde help improve plastic foaming and injection-molding operations

MURRAY HILL and NEW PROVIDENCE, N.J., March 10, 2014 /PRNewswire/ -- Plastic foam manufacturers and gas-assist injection molders (GAIM) can improve efficiency and quality with the help of a new liquid carbon-dioxide (LCO₂) pressure booster, PRESUS™ C system, from Linde North America LLC.

PRESUS C systems can supply high-mass-flow LCO₂ at a constant high pressure to a variety of industrial processes. Applications include high-performance spot-cooling of hot spots in plastic injection molds, and the supply of bubble-free LCO₂ to metering systems such as the DSD 500 for the physical foaming of polystyrene (PS) and low-density polyurethane (PUR). The PRESUS C system can also supply high-mass flow for precision surface cleaning with dry ice particles, such as with the CRYOCLEAN^® Snow system, which can clean and polish molds and OEM parts without water or ozone-depleting solvents.

Designed for precision and long service-life, the PRESUS C system automatically adapts to process demands.  During pauses in production, the LCO₂ mass flow will automatically stop to conserve cryogen and reduce energy consumption.  Pneumatic operation and a dual-pump design enhance reliability and flexibility. During service or maintenance, the parallel pump can continue to supply LCO₂ on a continuous basis to avoid interruptions in production.  

Three compact models are available: the PRESUS C8 pressure booster can deliver LCO₂ mass-flow rates from 10 to 220 lbs/h and operating pressures up to 1160 psi; the PRESUS C10 system can deliver the same mass-flow rates at pressures up to 1450 psi; and for heavy-duty industrial applications the PRESUS C50 system delivers LCO₂ mass flow from 65 to 1100 lb/h at pressures up to 1015 psi. The compressor systems feature high-efficiency, low-noise operation, and are available with automatic switching and temperature conditioning options.

The PRESUS C system is one of a range of high-tech gas supply and control systems for the plastics industry. The Linde Plastics Team reviews processing challenges and develops solutions for injection-molders, foamers and extruders, as well as manufacturers and designers of plastics processing equipment.
